Rezumat: Statistical Landslide Hazard Analysis in Solca Catchment Area. This paper proposes the use of a Geographical Information Systems (GIS) database in order to describe the statistical relations of landslide frequency and physical parameters, which contribute to the initiation of landslides on Solca catchment. This GIS database is used to obtain a susceptibility model for predicting slope instability. Here an inventory map of 29 landslides was used to produce a dependent variable. Slope angle, fragmentation depth, drainage density, slope curvature, slope aspect, land use and elevation were taken as independent variables. The effect of each parameter on landslide occurrence was assessed from the corresponding coefficient that is calculated by Landslide Index Method (LIM). Using a predicted map of probability, the study area was classified into six categories of slope susceptibility. The high susceptibility zones make up 6.7% of the total study area and involve mid-altitude slopes in the central part of Solca catchment. Keywords: susceptibility, GIS, landslide, catchment, LIM. |
